Check out the clearance section at Macy's where I found a variety of throw blankets with prices starting at just $8.96. I even found a heated throw for only $29.93. No promo codes are needed, but since these are on clearance, they can sell out at any time. Hurry and grab these deals while they last.
Make sure to sign up to become a Macy's Star Rewards member so you can get it shipped with a lower $25 threshold. You usually have to spend $49 or more for free shipping, so signing up saves you money.
